A monolithic and flexible fluoropolymer film microreactor for organic synthesis applications [PDF]

, 2019
A photocurable and viscous fluoropolymer with chemical stability is a highly desirable material for fabrication of microchemical devices. Lack of a reliable fabrication method, however, limits actual applications for organic reactions.

Preparation of highly active phosphated TiO2 catalysts via continuous sol–gel synthesis in a microreactor [PDF]

, 2019
Microreactors, featuring μm-sized tubes, offer greater flexibility and precise control of chemical processes compared to conventional large-scale reactors, due to their elevated surface-to-volume ratio and modular construction. However, their application

Stereo- and Enantioselective Addition of Organolithiums to 2-Oxazolinylazetidines as a Synthetic Route to 2-Acylazetidines

Frontiers in Chemistry, 2019
A new synthetic route to N-alkyl-2-acylazetidines was developed through a highly stereoselective addition of organolithiums to N-alkyl-2-oxazolinylazetidines followed by acidic hydrolysis of the resulting oxazolidine intermediates. This study revealed an

Co-precipitation continuous synthesis of the Ni-Rh-Ce0.75Zr0.25O2-δ catalyst in the membrane dispersion microreactor system for n-dodecane steam reforming to hydrogen

, 2021
Precipitation at the micro-scale to produce nanoparticles with small particle size and uniform dispersion is feasible. A membrane dispersion microreactor (MR) - matching spiral tube system was used to synthesize highly dispersed (MR)-Ni-Rh-Ce0.75Zr0.25O2-
